Control one- and two-speed heaters and air conditioners.

Commonly used with hydronic heaters, this thermostat senses the temperature of liquids. The thermowell protects the sensor.

Use to regulate line-voltage HVAC systems where flammable gases, vapors, and dust are present. Thermostats are rated Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G.

These thermostats are rated NEMA 4X for protection from dirt, washdowns, and corrosion.

These thermostats work with low-voltage HVAC systems that have only one speed.

Connect to a Wi-Fi network so you can remotely program, monitor, and control the temperature from a computer, tablet, or smart phone.

As the temperature goes up, the pressure in the system goes down.

When duct airflow varies from the setpoint, these actuators open and close until the system requirement is restored.

Often used to detect clogged air filters and iced air conditioner coils, these switches sense small changes in pressure between two points in your duct.

Operate equipment that cycles on and off from your control cabinet.

Also known as barometric dampers, these dampers improve furnace performance by automatically opening and closing to maintain consistent airflow despite changing environmental conditions.

Regulate airflow by adjusting dampers from fully open to fully closed.

Often used for electric-to-gas conversions and renovations, these exhausters allow gas- or oil-fired equipment to be vented through a sidewall rather than a chimney.
